Be it known that I, THOMAS WV. HoUoHrN, of Worcester, in the county of Worcester, in the State of Massachusetts, have invented certain new and useful Improvements in Paper-Cutting Machines; and I do hereby declare that the following is a clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification, in which- Figure l represents a side view, and Fig. 2 an end view.

A represents the frame of the machine, and which is usually made of cast iron.`

B is a base to which the frame A, in this instance, is attached by means of screws y', passing through the feet 7c ofthe frame A.

The paper to be cut, is` placedupon the top of the frame, (which is covered to form a table,) as shown at d in the drawings. The paper is held down iirm on the table while being cut by means of a platen or pressing plate F.

The platen or pressing plate F, is oper-` ated by means of the handle or lever E and screw D the lower end of screw D being fitted into the lower part of platen F, as shown in dotted lines Fig.`1, so that while the screw D is free to` turn, its connection with the platen F is such that its ascent or descent causes the platen to rise or fall.`

The upper end of D is smooth, where it works through F, but by turning the handle or lever E the screw D is made to rise or fall together with the platen` or pressing plate F, in consequence of screw D working in a female screw in the top piece C, which is fastened permanently to the frame` A, as

shown in Fig. 1, and braced as shown at C',`

Fig. 2. It will thus beseen that by simply turning the handle E, after the paper `has been placed in the proper position to be cut, the platen or pressing plate F can be forced down onto the paper, so as to hold it firm in place.

A gage`b is attached to the `table part of" the machine and is provided with a set O r thumb screw c, whereby the paper can be gaged before being cut. The paper is `cut by means of a knife H, which is attached` to slides I, I, or to a cross head tted to` said1 slides, and so arranged as to work close `up against the'plate F. i, `55 The necessary motion is `communicated ,to knife H by means of power applied toshaft g, to which is attachedagear1N,which`3 works into gear M on shaft K, both shafts, g and K being properly supported in bearl., ings in the frame A. Asthe shaft `Kis re-f i volved a reciprocating motionis `imparted to i the slides I, I, to which,theknifeI-Ifisatf tached by `means of `eccentrics f, f,q(whichg are rigidly keyed to `shaft K, `land arranged as shown in Fig. l) andVcoupling armsor` links J, J, the lower ends of coupling arms J, J, being fitted tojturn` loosely at e, onw the connecting bar` L, whichnnitesthe lower 1 ends of the slides I I, as shown indotted and full lines Fig. `1. i by N The slides I, I, are fitted to` slideup and 1 down on the inside of the `ends of the frame. f A, while the ends of the lframeare slotted f out so as to permit` the ends of the connectf` "7 ing bar L, together `with thenuts, by which` f the slides I, I, are fastenedto it, to have free play up and down. Thejcoupling arms J ,J are Vibrated by the` ,actionof` theeccentri while at the same timel they are raise and lowered. l It will be seen that the machineiabove d scribed is not only simple construction i but at the same time a very` powerful an effective one. pp" y, 'Ihe knife H is so connected with theyl slides I, I, that it can be adjusted by means;` of the nuts e, e, to set the edge thereof nearer.,` to or fartherfromthecutting `plate a, of* soft metal, which is" supported `on, bed` plate G. The knife is to be setfsoas tot just cut;` through the paper into the soft metalyand thus allow the gearing and shaft-s forworklfl ing the slides to be revolvedA continuously `in one direction. yIn this `waytthepower"apf",` plied to cut the paper continues `to act` to `i raise the knife for another1cutlwhile at the@l same time the power of theeccentrics just f at the moment of the iinal cut, isvery great and does not fail toproduce afcleanrlandf` perfect cut of the bottom sheets. The machine may be operated by the han-` i, dle z, in the side of the balance `wheel or 11 in any other manner.

The gears N, M, may be varied in size to with conpling arms J J, eccentrics f, f, and Suit the general character of the Work to be shaft K, substantially as and for the pur- 10 peormedl d poses set forth. y aving escribe my improved aper cut- 5 ting machine, What I claim therein as neviT THOS W HOUCIN' and desire to Secure by Letters Patent, is: Witnesses:
